Considering the production of NTD-silicon our interest is focussing on market growth, application fields and questions like reactor capacity, costs and material quality. Market growth still is in a further steady increase and since IC application particularly CMOS devices are not expected to turn over to NTD-silicon there is plenty of reactor capacity available to follow the market increase in power device application.

Further development of NTD-silicon is discussed regarding maximum diameter, upper resistivity limit and quality aspects.
